How much am I missing by racing with a joystick? In some ways, it's like a wheel because it has dynamic axises (compared with just "full on" or "full of" with a keyboard), but in other ways it's not because there are no pedals, no gearbox. What's your take?

One of the best Aussie drivers uses a joystick because he keeps breaking wheels, so I'd say it's pretty damn good if you're comfortable with it.
